Hardwire PDM 15 Power Distribution Module, an awesome unit that's designed to replace the conventional relays and fuses in a vehicle electrical system.

The Hardwire PDM 15 takes inputs from physical switches, analogue voltages, or the CAN bus, and provides power to different electronic devices such as radiator fans, fuel pumps and head lights. The current drawn from each connected device is continuously monitored. If the measured current is too high due to a fault, the PDM switches off the respective output to prevent further damage to the wiring loom or the connected device. If the fault persists, the PDM can retry the output.

Advantages Over Fuses and Relays

  • Greatly simplifies system wiring and reduces system component count.
  • Reduces the weight of the electrical system.
  • Provides increased reliability over traditional systems using mechanical relays.
  • Solid state technology removes the problem of relay contact corrosion and relay bouncing in vibration heavy applications.
  • Smart features such as indicator and wiper motor modes remove the need for extra control units.
  • Current draw can be monitored and logged to pre-emptively detect faults.
